FMUSER STL-10 Radio Studio Transmitter Link Stereo Transmitter and Receiver
*Synthesized from 220 to 260MHz, 300 to 320MHz, 320 to 340MHz,400 to 420MHz and 450 to 490MHz
*The transmitted and received frequency can be easily set by digital front panel
*Suitable for digital audio. The subsonic over modulation and the low frequency phase distortion are controlled by a feedback circuit in order to exalt the audio quality of the latest digital systems.
*Low THD distortion: the THD value with stereo or mono demodulated and deemphasized signals is negligible.
*Flat frequency response: due to the latest generation technology and the components precision the flatness of frequency response is absolute.
*Low noise: the excellent signal to noise ratio either in mono or in stereo allows the use of this STL in multi-hops networks without decreasing the audio quality.
*High sensitivity: it allows to reduce the STL’s antennas investment.
*Great RF immunity: allows to operate in most hostile RF environments.
*High adjacent channel rejection: obtained thanks to the excellent mechanical shielding and the precision of RF filtering.
*High frequency stability with the internal temperature compensated crystal reference.
* Integrated LCD Display: complete diagnostic and measurement front panel LCD displays.
*Integrated information display and protection controls: for all transmit parameter and protection for malfunction.
